Specifies the days of the month on that the mission should be scheduled for execution.
See also CONFCAL and WDAYS.
Figure 307 DAYS Parameter Format
Optional. The DAYS parameter specifies days of the month on that missions should be scheduled, provided other basic scheduling criteria are met. Values for DAYS can be specified alone, or they can be specified in conjunction with a calendar specified in the DCAL parameter. DAYS and DCAL can also be specified in conjunction with WDAYS and WCAL (described in WDAYS: Mission Definition Parameter).
DAYS subparameters are described in Table 282.
Table 282 DAYS Subparameters
Subparameter |
Description |
---|---|
DAYS |
Days of the month on which to schedule a mission. The months in which to order missions are specified in the MONTHS parameter, which is described in MONTHS: Mission Definition Parameter. Various formats (described below in "Valid Formats for the DAYS parameter") can be used to specify DAYS (for example, 3 means the 3rd day of the month, L2 means the day before the last day of the month, D1PA means the 1st day in period A). |
DCAL |
Name of a calendar containing a predefined set of dates (referred to as working days) on that a mission should be scheduled. A specified name must be a valid member name of 1-8 characters, or an * to indicate that the calendar specified in the CONFCAL parameter should be used for scheduling. For more information on how to define, use and modify calendars, see IOA Calendar Facility. |
Note: A calendar specified in DCAL does not have to exist when defining mission parameters. However, it must exist when the mission is ordered. |
|
AND/OR |
Conjunctional parameter used to link the DAYS and WDAYS parameters when both are specified. |
A (AND) |
Both DAYS (and DCAL) and WDAYS (and WCAL) criteria must be satisfied to schedule a mission. |
O (OR) |
Either DAYS (and DCAL) or WDAYS (and WCAL) criteria must be satisfied to schedule a mission. Default. If A (AND) is specified when either DAYS or WDAYS is specified (but not both), the missing DAYS or WDAYS value is automatically set to ALL. |
Assuming all other Basic Scheduling criteria are met:
Valid Formats for the DAYS parameter
Valid formats for the DAYS parameter, and how they relate to DCAL, are described below.
In the following non-periodic scheduling formats:
Table 283 Non-Periodic Scheduling Formats
Format |
Description |
---|---|
ALL |
All days of the month. If ALL is specified, other DAYS values cannot be specified with it. |
n,... |
Specific days of the month. |
+n,... |
Days of the month in addition to the working days specified in the DCAL calendar. DCAL is mandatory. |
–n,... |
Schedule the mission on all days except the nth day from the beginning of the month. DCAL is mandatory. |
>n,... |
Schedule the mission on the indicated day if it is a working day in the DCAL calendar. Otherwise, schedule the mission on the next working day that is not negated by a –n value in this parameter. This format is frequently used for holiday handling. DCAL is mandatory. |
<n,... |
Schedule the mission on the indicated day if it is a working day in the DCAL calendar. Otherwise, schedule the mission on the last previous working day that is not negated by a –n value in this parameter. This format is frequently used for holiday handling. DCAL is mandatory. |
Dn,... |
Schedule the mission on the nth working day from the beginning of the month. DCAL is mandatory. |
–Dn,... |
Schedule the mission on all working days except the nth working day from the beginning of the month. DCAL is mandatory. |
Ln,... |
Schedule the mission on the nth day (or nth working day if DCAL is defined) counting backward from the end of the month. DCAL is optional. |
–Ln,... |
If DCAL is defined, schedule the mission on all working days except the nth working day counting backward from the end of the month. If DCAL is not defined, schedule the mission on all days except the nth day from the end of the month. DCAL is optional. |
